Synthesis and UV Curing Properties of (Meth)acrylated Dendritic Poly(ether-amide)

Abstract

Abstract: Dendritic polymers have received increasing interests from polymer scientists because of the unique structural characteristics, synthetic methods as well as application fields. The (meth)acrylated dendritic poly(ether-amide)s were synthesized by a divergent manner and characterized by ¹H NMR, VPOand FTIRmeasurements. Their UVcuring properties were investigated by Raman, Photo-DSCand DM-TAmeasurements. Over 80% of unsaturation conversion has been obtained for the systems in the presence of a photoinitiator under UVirradiation, and the polymerization rate at peak maximum was promoted with increasing the concentration of double bonds. The softening and glass transition temperatures of their UVcured films were also promoted with increasing the concentration of double bonds.

Key words: Dendrimer, Poly(ether-amide), UV curing, Kinetics, Thermomechanical property
